Photographic processing composition in slurry-form

In a slurry-form photographic processing composition, some of photographic processing components are dispersed in water in fine particulate form, and a water-soluble polymer is contained in an amount of 0.1-10% by weight based on the weight of the processing components. The slurry composition is compact, easy to take out of the container, well soluble, and free of degradation during long-term storage.

Claims

1. A slurry-form photographic processing composition comprising

photographic processing components, some of which are dispersed in a medium in fine particulate form, and
0.1 to 10% by weight based on the weight of said processing components of a water-soluble polymer, wherein said water-soluble polymer has a degree of etherification of at least 0.8.

2. The slurry composition of claim 1 having a viscosity of 0.1 to 100 poise as measured at 25.degree. C. and a low shear rate by a Brookfield viscometer.

3. The slurry composition of claim 1 wherein an aqueous solution of 1% by weight of said water-soluble polymer has a viscosity of 1 to 150 poise as measured at 25.degree. C. and a low shear rate by a Brookfield viscometer.

4. The slurry composition of claim 1 wherein said water-soluble polymer is selected from the group consisting of a cellulosic resin, polyvinyl alcohol, polyvinyl pyrrolidone, acrylic resin, polystyrene sulfonate resin, and modified products thereof.

5. The slurry composition of claim 4 wherein said water-soluble polymer is carboxymethyl cellulose or a modified product thereof.

6. The slurry composition of claim 5 wherein said water-soluble polymer is carboxymethyl cellulose or a modified product thereof.

7. A method for processing a silver halide photosensitive material, comprising the steps of:

diluting the slurry-form photographic processing composition of claim 1 with water to form a processing solution,
imagewise exposing a silver halide photosensitive material, and
processing the exposed photosensitive material with the processing solution.

8. The method of claim 7 wherein in the diluting step, the slurry composition is diluted with water by a volume factor of 3 to 10.
